I just found out, that my account page is not working anymore. When I click e.g. on “Billing” History, it will always go to the account page. I saw that there is an update (1.5.4) of the ThemeVan Core plugin required and available (hoping, that this will fix the bug). When i want to update the plugin, it says “The plugin is at the latest version. Plugin not activated. A higher version of ThemeVan Core is needed for this theme. Please update the plugin.” wtf!?? How can I fix this? Please help!!
